关节镜监视下髌骨环治疗髌骨粉碎性骨折的临床应用

Clinical application of arthroscopic assisted patellar ring in treatment of comminuted patellar fracture

目的：研究关节镜辅助下利用髌骨环治疗粉碎性骨折的可行性和安全性,为临床应用提供理论指导.方法：对照组采用传统切开复位方式,采用克氏针张力带固定.观察组采用关节镜的方式,利用髌骨环固定.对患者术后1年的恢复情况进行随访.计算有效率和并发症发生率.结果：对照组有效率为70%,观察组有效率为94%,二者差异具有统计学意义.认为髌骨环的治疗效果显著优于克氏针张力带.对照组并发症发生率6%,观察组没有发现明显的并发症,二者差异具有统计学意义.结论：髌骨环的治疗效果更加安全可靠.

Objective： To study the feasibility and safety of arthroscopic treatment of comminuted fracture with patellar ring, and to provide theoretical guidance for clinical application. Methods： the control group was treated with traditional open reduction and Kirschner wire tension band fixation. In the experimental group, the patellar ring was fixed by arthroscopy. The patients were followed up for one year after the operation. Computational efficiency and complication rates were calculated. Results： the effective rate of the control group was 70%, the effective rate of the experimental group was 94%, and the difference between the two groups was statistically significant. It was considered that the treatment effect of patellar ring was better than Kirschner wire strap. The incidence of complications in the control group was 6%, and no obvious complications were found in the experimental group, and the difference between the two groups was statisti- cally significant, it was considered that the treatment of patellar ring was safer and more reliable.
